Mass versus Weight
In everyday use, "mass" usually has the same meaning as "weight"; however, in physics, those words represent two different concepts:
Mass
Refers to an elemental property of an object. It's the amount of "matter" in an object. We usually measure it in pounds or kilograms. Mass remains constant regardless of location.
Weight
Refers to the force acting on the object due to gravity. It measures an object's resistance to deviation from its natural course of free fall. It is usually measured in pounds-force or Newtons.
For example, 1 kilogram of chocolate has a weight of about 9.8 newtons on the surface of the Earth. Its weight will be smaller on Mars (as the gravity is weaker), but greater on Saturn. The mass, however, will always be the same.
Units of Mass
The standard International System of Units (SI) unit of mass is the kilogram (kg). However, remember that the SI prefixes for different masses use the unit gram as their base, not the kilogram. We listed some examples below:
Metric Units (SI)
- • Microgram (µg) — 0.000001 g
- • Milligram (mg) — 0.001 g
- • Gram (g) — base unit
- • Decagram (dag) — 10 g
- • Kilogram (kg) — 1000 g
- • Megagram/Tonne (t) — 1,000,000 g
Imperial Units
- • Grain (gr) — 1/7000 lb
- • Ounce (oz) — 1/16 lb
- • Pound (lb) — base unit
- • Stone — 14 lbs
- • Ton — 2240 lbs (UK) or 2000 lbs (US)
U.S. units are similar to the imperial system; however, there are some differences, e.g., there is no "stone" and a ton equals 2000 lbs.

How to Use Grams to Ounces Calculator — An Example: 100 Grams to Ounces
We can use a practical example to make sure that everything is clear. Let's say that you have a recipe for a delicious cake that requires 100 g of butter 🧈 Unfortunately, your scale measures in ounces, so you want to convert 100 grams to ounces.
You can, of course, use our grams to ounces calculator to do it quickly without thinking too much. But there are some cases where you need to do it by hand. So, how can you convert 100 grams to ounces? You need to use the following equation:
Formula:
X ounces = Y grams / 28.34952
So:
X ounces = 100 / 28.34952 = 3.53 ounces
So, the 100 grams to ounces conversion is: 3.53 ounces ⇔ 100 grams
There we go. 100 grams of butter is the same as 3.53 ounces of butter.
